Application filed May 4, 1920. VSerial No. 378,839.

To all whom t 'may concern Y Be it known that I, EUGENE HAGGERTY, a

citizen of the United States, residing at Clifton Springs, in thecounty of Ontario' K vide novel means whereby the shoe of a grain drill may be raised either by lpower derived from the ground wheel, or by hand, and the inventori aims particularly to improve, the mechanism whereby the shoe is raised by the action of the ground wheel,

and to provide means whereby each of the raising instrumentalit'ies may operate without interfering with the other.

The invention aims to improve generally l and to enhance the utility of devices of that type to which the invention appertains, and, within the scope of what is claimed, a mechanic may work changes, without departing from the spirit of the invention.

In the drawings Figure 1 shows inside elevation, a device constructed in accordance with the invention, parts appearing in section; Fig. 2 is a top plan wherein parts are broken away; and Fig. 3 is a sectional detail disclosing sundry elements which are located on the axle.

The device forming the subject matter of this application mayform part of grain drills of widely different sorts,but in the drawings, the numeral 1 denotes a frame having bearings 20 wherein an axle 2 is journaled, the axle carrying ground wheels 3, as usual. A planter shoe4 is shown and is suspended at 5 from the frame 1 for vertical swinging movement toward and away from the surface of the ground. A shaft -6 is journaled in bearings on the frame 1.

The shaft 6 is supplied with an arm 7 connected by any suitable means 8 with the shoe 4, the construction beingl such that when the shaft 6 is rotated, the shoe 4 will be raised, all of the foregoing being more or less common.

The invention contemplates the provision of means whereby the shaft 6'may be rotated either by the ground wheel 3, orby hand. Two different but coperating means are provided, therefore, for raising and lowering the shoe 4 by way of the shaft 6.

IConsidering, means for operating the shaft V6, it will be Specification of Letters Patent:

first, the wheel-actuated -pointed out hereinafter.

observed that a bracket 9 is attached to one l side portion ofthe frame 1, by means of one of thebearings 20, if desired, as shown'i'n Fig. 3. The bracket 9 is supplied with in'- wardlyprojecting arms 10 and 11.' One end ofa lever 12 is pivoted at 14 to the arm 10, the other end 15 of the lever sliding on the arm 11.. Intermediate its ends, thelever 12 is provided with an eye 16 having lugs 17 coperating with the iange 19 of a sleeve 18 rotatable within the eye 16 and splined at 21 to the axle 2 to rotate therewith and to slide therealong.

A pinion 22 is rotatable on the axle 2 and is held againstk sliding movement longitudinally of the axle by a set collar 23 and a shoulder 24 on the axle. There is a" projection 26 on one end of the hub of the pinion 22, the projection being adapted to coperate with a projection 25 on the end ofthe sleeve 18, the sleeve and the projections constituting, effect, a clutch whereby the pinion 22 may be connected to the axle to rotate therewith.

A cam or actuating member 27 is pivoted at 28, intermediate its ends, to the arm 11 of the bracket 9 and bears at one end upon the end 15 of the lever 12. A retractile spring 29 is connected at its ends to the arm 11 of the bracket 9 and to the cam 27 at one'side of the pivotalmouiiting 28 ofthe cam.v An operating element30'is pivoted to the cam 27 and may bein the form of a rod. A compression spring 100 is interposed between the bracket 9 and the sleeve 1.8 and constitutes means for advancing the sleeve- 18 'so that the projection 25 on the sleeve will lie in the path ofthe projection A26 on the pinion 22. f "N The numeral 31 denotes a-loop-sha-ped rack bar supported on the pinion 22 and provided onjits lower edge with a rack 32 coacting with 'the pinion 22. The rackbar 31 has an'extension 33 provided with a slot 34 receiving a pivot 'element 35 `on an arm from the shaft. There is a stop 44 onthe frame, adapted to coact with the upperfend of the' lever 37, under. conditions toYV be An operatingV member 45 is 'connected to the lower end of;

provided with a slot 48 receiving a projec- 'tion 49 on the lever 37. The rack bar 31 has a side projection 50 adapted to copcrate with the cam or actuating member 27.

The foregoing concludes the description of the means whereby the shaft 6 may be operated from the wheel 4, and before taking up the description of the means whereby the shaft 6` may be actuated by an operator, the way in which the shaft 6 isV controlled from the wheel 3, will be explained.

Supposing that the parts 12, 27 and 18 are arranged as shown in Fig. 2,'it will be understood that when the axle 2 is rotated by the ground wheel 3, the sleev-en18 will be rotated also, the projection on the sleeve coacting with the projection'26 on the hub of the pinion 22, to impart rotation to the pinion. When the pinion 22 is rotated, the pinion will'move the rack bar 31 in the direction of the arrow A in Fig. 1, and when the rack bar moves as aforesaid, the pivot ele- Vment will arrive at the end of the slot 34 inthe extension 33 of the rack bar, rotation being imparted to the shaft 6 by way will swing the shoe 4 upwardly on its pivotal mounting 5. When the rack bar 31 is moved .in the direction of the arrow A, as afore- Y said, the projection 50 on the rack bar engages the cam 27 and tilts the cam on its pivot 28, the cam coperating with the end 15 of the lever 12 to swing the lever on its fulcrum 14 and to slide the sleeve 18 on the shaft 12 until the projection 25 on the sleeve no longer is in the path of the projection 26 onl the hub Yof the pinion 22. The axle 2 may `now continue to rotate withv the ground 40 now coperates with the arm 43 on the shaft 6to prevent the shaft from rotating vvand to prevent the shoe 4 from being lowi ered.

When it is desired to lower the shoe 4, the operating member 45 is pulled upon, thus moving the lever v37l from the dotted line Lposition of Fig. 1 to the solid line of that figure, the upper end of the lever moving out of engagement with the stop 44, and the toggle lock afforded by the lever 37 andV the link 40 being broken. The link 40 no longer restrains the shaft 6 against rotation, and

vthe shaft may rotate, the arm 7 swinging downwardlyiand `effecting a lowering kof the shoe 4. When the lever 37 is swung from the dotted line position of Fig. 1 to the solid line position of that ligure, the link 46 moves the rack bar 42' from the dotted line position to the solid line position, such an operation being possible because the pinion 22 can rotate on the axle 2, it being recalled that the sleeve 18 is held retracted by the lever 12 and the cam r27. The cam 27 is now swung on its pivot 28 by means of the Voperating element 30, which, like the part A45, is immediately under the control of an operator. -The effort of the spring' 29 is overcome and the parts are restored to the position of Fig. f

2, the sleeve 18 being-advanced by the spring 100, the sleeve being no longer held retracted by the lever 12, since the cam 27 has been restored to the position shown in Fig.. 2. The projection 25 onthe sleeve 18 now lies in the path of the projection 26 on the hub of the pinion 22, and when the axle 2 is rotated rby the Vground wheel 3, the rack bar 31 will be operated, and the shoe 4 raised, as hereinbefore set forth.

The mechanism for raising the shoe by the operation of the ground wheel 3, and the operation of that mechanism, have been set forth. The means for raising'the shoe 4 byv hand -will now be described.

A segment 51 is carried by the frame of the machine, a lever 52 being vfulcrumed at 53 on the lower portion of the segment. The lever 52 carries a latch 54 adaptedto coperate with the notches 55ern the segment 51. The lever 52 is connected by a link 72 with' the arm 36 of the shaft 6. lA U-shaped slide 56 is mounted for vertical reciprocation on the segment 51, the slide having elongated slots 57 receiving headed securing elements 58 mounted in the segment 51. I An actuating member in the form of a bar"59 is mounted for right line reciprocation on the securing elements 58 and is held thereon, against lateral displacement by the heads of the securing elements. ln the upper edge of the bar 59 there are inclined notches 61 coperating with pins 62 carried by the Vslide 56. A link 63 connects the bar or actuating member 59 with the extension 33 of the loop-shaped rack bar 31.-

The lever 52 may beswung on its -fulcrum 53, the link 72 rocking the shaft 6 to effect a raisingor a lowering of the shoe 4 by way of the parts`7 and 8. Since the arm 36 is connected to the rack bar 31, the rack bar will be .fmoved in the direction of the arrow A in Fig. 1, when the lever 52 is operated as above described, the rack bar and the pinion 22 in no wise interfering with the operation ofthe structure by hand, since the pinion is free to rotate on the axle 2, saving when the sleeve 18 is advanced,

j as in Fig. 2, so that the projections 26 Vand 25 coperate.

When the shoe 4 is' raised bythe action of the wheel 3, the rack bar 31 moves in the direction of the arrow A. The link 63 slides the actuating member or bar 59 in the direction of the arrow A, the inclined portions of the notches 6l in the bar coperate with the pins 62 in the slide 56; the slide moves upwardly on the securing elements 58; and the crown of the slide engages the latch 54 on the lever 52 and disengages the latch from the corresponding notch 55 in the segment 5l. The lever 52, therefore, is free to swing responsive to the link 72 and the arm 36 when the motion for raising the shoe 4 is derived from the ground wheel 3.

I claim l. In a grain drill, a frame; a shaft mounted to rock on the frame; a shoe; means for connecting the shoe with the shaft whereby the shoe will be raised when the shaft is rotated;`a ground wheel carried by the frame; means for rotating the shaft from the ground wheel; mechanism under the control of anvoperator for rotating the shaft; a latch restraining said mechanism; and a latch-releasing device operated by the means for rotating the shaft from the ground wheel.
